Borehole geophysical logging methods are used to measure physical properties of geologic material around the borehole, borehole fluid properties, and the integrity of well construction materials. Downhole tools manufactured by Mount Sopris directly measure or allow us to draw...

Mount Sopris slimline probes and easy-to-use portable geophysical logging systems are ideally suited for shallow, near surface environmental applications, and were very popular in the 1990’s when the US EPA implemented facets of the Clean Water Act and CERCLA. Today our...

Many University R & D programs focus on the fact that rocks are inherently complex, heterogeneous porous systems. Few problems in shallow geophysical logging are independent of pore spaces, pore fluids and rock-fluid interactions. Mount Sopris tools are used as part of R...

Electric well logging was invented in 1926 and has been used in the oil & gas industry since that time. Over the years numerous other downhole measurements have been applied in the energy exploration and production community. Mount Sopris manufactures many of the classical...

About Mount Sopris

Mount Sopris Instrument Company was founded in Boulder, Colorado in 1951 at a time when locating uranium for weapon and reactor use was of national interest. The company’s first product was a portable scintillation counter. Early on, Mount Sopris joined forces with another Colorado company, one that made respirators for use by polio victims.
